1. A magnetic inductance tomography (MIT) device for imaging a tissue of a patient, the MIT device comprising:
a plurality of coils comprising a first coil and a second coil;
an electronic circuitry configured to separately energize individual coils of the plurality of coils to generate magnetic fields perturbed by a tissue of a patient;
an elongate member coupled to the plurality of coils and configured to move in a reciprocating manner to vary a distance of the plurality of coils from the tissue; and
one or more processors configured to:
receive MIT signals responsive to the magnetic fields perturbed by the tissue, the MIT signals comprising a first MIT signal generated by the first coil and a second MIT signal generated by the second coil, the first MIT signal being indicative of a characteristic of the tissue at a different depth in the tissue from a surface of the tissue than the second MIT signal, and
process the MIT signals to generate an MIT image.
